Computation Theory Lecture notes
The aim of this course note is to introduce several apparently different formalisations of the informal notion of algorithm; to show that they are equivalent; and to use them to demonstrate that there are incomputable functions and algorithmically undecidable problems.

Theory of Computation by Kyle Burke
This pdf begins with an overview of resources, organization and motivation and preview of CS theory covering the Limits of Computation, the Undecidability of the Halting Problem.The Automata and Machines including Deterministic and Nondeterministic Finitestate Automata, Pushdown Automata, and Turing Machines and Language Classes. Finally focus shifts to Computational Complexity, discussing NPCompleteness, Approximation Algorithms, and the Hardness of Approximation.

Theory of Computation Tutorials
This set of tutorials goes into the heart of the theory of computer science with formal languages and automatons, computability, and complexity. Topics to be discussed are regular and contextfree languages, finite automata, and pushdown automata. Consequently, resulting tutorials treat topics like Turing machines, Churchs thesis, and the problem of undecidability, whose examples include the and quot,halting problem and quot, in the exploration of the limits of computability. They look into complexity classes such as P, NP, and PSPACE, look into NPcompleteness, or provide an indepth treatment along with a wide introduction to the theoretical foundations of computer science.
